Understanding Your Flight Itinerary: The Cornerstone of Travel Planning
To look up your flight itinerary, you typically need your booking reference number (also called a confirmation code or PNR) and your last name. Access your airline's website or mobile app, navigate to the 'Manage My Booking' or 'My Trips' section, and enter these details. This will display your flight details, including dates, times, flight numbers, airports, and seat assignments.
- Access airline website/app with booking reference and last name.
- Use 'Manage My Booking' or 'My Trips' sections.
- Verify all flight details, dates, and times for accuracy.
- Confirm terminal, gate, and seat assignments if available.
The flight itinerary is more than just a confirmation; it is your official record of travel arrangements. It contains all the essential information required for your journey, from departure and arrival times to specific flight numbers and passenger details. Misplacing or misunderstanding this document can lead to significant travel disruptions, such as missed flights, incorrect check-ins, or confusion at the airport. Proactively understanding how to access and interpret your itinerary is a fundamental skill for any traveler, ensuring a smoother and less stressful experience from booking to touchdown.
Many travelers assume their itinerary is a single, static document that arrives once and is then set in stone. In reality, minor changes can occur, and having the ability to re-verify details is paramount. This proactive approach allows you to catch potential issues, such as schedule adjustments or gate changes, before they impact your travel plans. It also equips you with the necessary information to manage your booking, such as pre-selecting seats or arranging special assistance.
When you book a flight, especially with online travel agencies (OTAs) or through third-party sites, you might receive an initial confirmation email that looks like an itinerary but may not contain all the granular details or direct links to manage your booking. It's vital to distinguish between a booking confirmation and the official flight itinerary provided directly by the airline. The latter is your authoritative source for all flight-related information.
This article focuses on preventing common mistakes associated with managing and accessing flight itineraries. By understanding the typical pitfalls, you can adopt a more robust approach to safeguarding your travel plans.
The Importance of a Verified Itinerary
Your flight itinerary serves as the definitive proof of your travel arrangements with the airline. It validates your purchase and outlines the precise services you are entitled to. Without a clear, accessible itinerary, navigating the complexities of air travel becomes significantly more challenging. This document is your primary reference point for everything from checking in online to understanding baggage allowances and arrival procedures at your destination. Ensuring its accuracy and accessibility is a non-negotiable step in preparing for any trip.
Consider the itinerary as your travel passport for the flight segment of your journey. It confirms not only the flight number and times but also crucial details like the aircraft type, potential layovers, and any special notes from the airline. Having this information readily available means you can confidently proceed through each stage of your travel, from arriving at the airport to boarding the aircraft.
A well-managed itinerary also empowers you to take advantage of airline services. Many airlines allow you to add your itinerary to digital calendars or download it for offline access, which is invaluable when traveling in areas with limited connectivity. Furthermore, it's often required for other travel arrangements, such as hotel bookings or car rentals, where confirmation of your arrival time is necessary.
Common Pitfalls and Misconceptions
One of the most frequent mistakes travelers make is relying solely on a third-party booking confirmation email without cross-referencing with the airline's official record. These initial confirmations might lack critical details or could be outdated if the airline made a schedule change that wasn't immediately reflected. Another common error is not verifying passenger names, dates, and flight numbers for absolute accuracy. A single typo can render your booking invalid or cause severe problems at check-in or security.
Many travelers also fail to understand that their itinerary might be dynamic. Airlines sometimes adjust flight times or even flight numbers due to operational reasons, weather, or air traffic control. If you only check your itinerary once after booking, you might miss these crucial updates, leading to a shock at the airport. The expectation that a booking confirmation is final and unchanging is a significant misconception that can lead to travel mishaps.
Furthermore, not all booking platforms provide the same level of detail. Some might omit information about specific airport terminals, gate assignments, or even baggage allowances. This lack of comprehensive information in an initial confirmation can leave travelers feeling unprepared. The belief that all booking confirmations are equivalent to an official airline itinerary is a dangerous oversight.
Mistake 1: Not Knowing Where to Find Your Flight Itinerary
The most fundamental error is not knowing the primary sources for retrieving your flight itinerary. Many passengers mistakenly believe their itinerary is only in the initial booking email, which might be incomplete or outdated. The authoritative source is always the airline's own platform.
Primary Access Channels: Airline Websites and Apps
Your airline's official website or mobile application is the most reliable place to look up your flight itinerary. Once you have completed your booking, you will typically receive a booking reference number (also known as a confirmation code or PNR) and your last name. Navigate to the airline's homepage and look for sections like 'Manage Booking,' 'My Trips,' 'Check-in,' or 'Flight Status.' After entering your booking reference and last name, you should be able to view your complete itinerary.
This section is designed for travelers to manage all aspects of their booking. It allows you to confirm flight details, select seats, add baggage, update passenger information (within airline policy limits), and, most importantly, access your official itinerary document. Many airline apps also offer real-time updates on flight status, gate changes, and boarding times directly to your smartphone, making them indispensable travel companions.
It is critical to use the airline's portal for the most accurate and up-to-date information. Third-party booking sites may not always reflect last-minute changes made by the airline promptly.
Secondary Sources: Email Confirmations and Travel Agencies
While the airline's platform is primary, your initial booking confirmation email often serves as a starting point. This email usually contains your booking reference number and a link to manage your booking on the airline's website. If you booked through a travel agency (online or physical), they will also provide you with a confirmation, which should include your booking reference and airline details. It is imperative to find the airline's booking reference within these documents, as this is the key to accessing your itinerary directly from the carrier.
Some booking confirmations from third parties might include a summarized itinerary. However, these summaries can sometimes lack specific details like terminal information, baggage allowances, or the option to manage your booking. Always cross-reference any information from a travel agent or OTA with the airline's own system to ensure completeness and accuracy. If a discrepancy arises, the airline's record generally takes precedence.
What to Do If You Can't Find Your Booking Reference
If your booking reference number is missing from emails or documentation, your first step is to check the original booking platform. If you booked directly with the airline, review all correspondence from them. If you used a third-party site, check your spam or junk folders and search for emails from that specific retailer. If still unsuccessful, contact the customer service of the airline or the travel agency you booked through. They will be able to retrieve your booking reference by verifying your personal details, such as your name, travel dates, and email address used for booking.
Losing your booking reference is a common issue. This is why proactive saving of important travel documents is essential. Consider forwarding confirmation emails to a dedicated travel folder in your inbox or saving them in a cloud storage service. For a more robust solution, make a habit of noting down the booking reference and key flight details immediately after booking.
Mistake 2: Ignoring Key Details on Your Itinerary
A common oversight is treating the flight itinerary as a simple confirmation of dates and times, neglecting crucial details that prevent travel day confusion and errors.
Flight Numbers and Codes Explained
Each flight segment has a unique flight number, typically a two-character airline code followed by a number (e.g., UA123 for United Airlines). Understanding your flight number is vital for checking flight status, making changes, and for airport signage. Sometimes, flights might be operated by a codeshare partner airline; your itinerary should specify both the marketing flight number (the one you booked) and the operating flight number (the airline actually flying the plane). Always confirm which number is relevant for check-in and boarding.
Knowing the flight number allows you to track your specific flight in real-time. This is particularly useful if you are meeting someone at the airport or need to adjust your arrival time based on delays. Many flight tracking websites and apps use this number exclusively to provide up-to-date information on departure and arrival times, gate changes, and even aircraft location.
Verify that your itinerary clearly lists the correct flight numbers for each leg of your journey. A mismatch here can lead to boarding the wrong aircraft or showing up at the wrong gate.
Terminal and Gate Information: Navigating the Airport
Your itinerary may list the departure and arrival terminals at each airport. Airports, especially large international hubs, can be vast and have multiple terminals. Knowing your terminal in advance saves significant time and reduces stress. It also helps determine the best way to reach the airport and where to direct your taxi or rideshare. Some itineraries might even specify the gate number, though this is often subject to change and is usually confirmed closer to departure time or on airport screens.
Arrival terminal information is equally important, especially if someone is picking you up or if you have onward connections to make. Different terminals might have different customs and immigration facilities, or different baggage claim areas. Always check this detail, even if the gate number is not yet assigned.
Layover and Connection Details
For trips with multiple stops, the itinerary will detail layover times, connecting airports, and sometimes even terminal transfers. It's crucial to note the duration of layovers. A short layover (e.g., under an hour) can be stressful, especially if your first flight is delayed. Conversely, an excessively long layover might require you to consider lounge access or airport amenities. Ensure the connecting flight details are correct and that you have sufficient time to disembark, navigate the airport, and board your next flight.
Pay close attention to whether your connection requires a terminal change. Some airports have internal shuttles or trains for inter-terminal travel, which can take time. If your itinerary specifies the connecting flight number, double-check this against the departure boards at the airport, as gate assignments can change rapidly.
Passenger Information Accuracy
The itinerary will also list passenger names exactly as they appear on your booking. It is imperative that these names match your government-issued identification (passport, driver's license) precisely. Even minor discrepancies, like a missing middle initial or a transposed letter, can cause issues during check-in or security screening. You may be denied boarding if your name does not match your ID. If you find an error, contact the airline immediately to have it corrected.
Mistake 3: Not Verifying for Errors or Discrepancies
A significant error is assuming that a booking confirmation is automatically error-free. Failing to meticulously verify all details can lead to significant travel disruptions.
The Importance of Name Matching
As mentioned, passenger names must match your identification. This applies to everyone on the booking. If you booked for family members, ensure their names are entered correctly. For example, if a passport lists 'Maria Elena Rodriguez' and the booking has 'Maria Rodriguez,' this might cause problems. Many airlines will allow minor corrections, but it's best to get it right from the start. Always compare the itinerary against the primary form of identification you intend to use for travel.
Some systems might automatically truncate names or use abbreviations. It's your responsibility to ensure the full, correct name is present. If the itinerary shows a shorter version of your name, check if the airline has a policy on this or if you need to contact them for an official correction. The rule of thumb is to match what's on your passport or government ID exactly.
Never assume an airline will automatically fix a name discrepancy; take action yourself.
Date and Time Accuracy: AM vs. PM and Time Zones
Double-check all dates and times. Pay close attention to AM/PM indicators and confirm the time zone for departure and arrival cities. Many itineraries will specify local times for each city, but it's wise to confirm. A flight departing at 10:00 PM might be easily confused with 10:00 AM if you're not paying attention, potentially leading to a missed flight. Ensure you understand whether the times listed are local to the departure city or a universal time standard if not explicitly stated.
Consider time zone changes when planning your arrival. If you land at 2:00 PM local time in a city that is three hours ahead of your departure point, you've effectively been traveling for longer than the flight duration suggests. Understanding these shifts helps in planning ground transportation, hotel check-ins, and onward activities.
Baggage Allowance and Fees
Itineraries or associated booking details should clearly state your baggage allowance – how many checked bags are permitted, their weight limit, and size restrictions for carry-on luggage. Many airlines now charge for checked bags, and fees can vary based on the route, fare class, and number of bags. Not verifying this information upfront can lead to unexpected and often hefty charges at the airport counter. Some fare types may not include any checked baggage at all.
Make a note of these allowances and plan your packing accordingly. If you anticipate needing to check extra bags, research the cost of adding them in advance through the airline's website, as it's usually cheaper than paying at the airport. This detail is crucial for budgeting and packing efficiency.
fare Class and Seat Assignments
Your itinerary will indicate the fare class booked (e.g., Economy, Business, First Class) and any assigned seat numbers. While fare class determines your service level and benefits, seat assignments are often a separate selection or may be assigned at check-in. If you have a specific seat preference or need to make an assignment, ensure this is reflected in your itinerary or has been confirmed separately. Some fare types do not permit free seat selection.
If your seat assignment is missing or incorrect, this is another area to address with the airline promptly. For travelers with specific needs, such as those requiring extra legroom or accessible seating, confirming the seat assignment is paramount.
Mistake 4: Not Preparing for Itinerary Changes
A frequent error is assuming your itinerary is fixed, leading to surprise and inconvenience when airlines inevitably make schedule adjustments.
Why Airlines Change Flight Schedules
Airlines adjust flight schedules for numerous reasons: operational efficiency, aircraft maintenance, route profitability, crew availability, and sometimes due to external factors like air traffic control restrictions or demand fluctuations. These changes, while often minor (like a 30-minute shift in departure time), can sometimes be more significant, involving different flight numbers or even alternative airports. It's important to remember that the flight you booked is a service commitment, but the specific timing and aircraft can be subject to operational needs.
These adjustments are a normal part of airline operations. Understanding this helps in approaching itinerary management with a proactive mindset rather than one of surprise. The airline's obligation is to get you to your destination, but the exact timing and flight details can evolve.
How Airlines Notify Travelers of Changes
Airlines typically notify passengers of significant schedule changes via email or SMS, using the contact information provided during booking. However, relying solely on these notifications can be risky. Emails can go to spam folders, or phone numbers might be outdated. This is why actively checking your itinerary is crucial, especially in the days leading up to your flight.
Some airlines offer app notifications or alerts through their mobile platforms, which can be more reliable if you have push notifications enabled. Nonetheless, it's best practice to have a system in place that doesn't depend on a single notification method.
Regularly re-checking your itinerary is the most robust strategy against missed updates.
Strategies for Staying Updated
To avoid being caught off guard by itinerary changes, implement a routine check-in process. A good practice is to review your itinerary 72 hours before departure, again 24 hours before, and then again shortly before heading to the airport. Many airlines also allow you to 'add to calendar' or 'sync with my device,' which can help integrate flight details into your daily schedule and provide reminders.
Consider using flight tracking apps or websites that allow you to input your flight details (flight number, date) and receive real-time updates. If you frequently travel with a specific airline, ensure you are signed up for their loyalty program, as this often streamlines communication and management of bookings.
What to Do If a Change Affects Your Plans
If a schedule change significantly impacts your travel plans (e.g., causes you to miss a connection, arrive too late for an event, or makes the new timing inconvenient), contact the airline immediately. They may offer alternative flights, rebooking options, or, in some cases, a refund if the change is substantial and you decide not to travel. Be prepared to explain how the change affects your specific needs.
Document all communications and agreements with the airline. If you are rebooked, ensure the new itinerary reflects the agreed-upon changes accurately. If you are offered compensation, understand the terms and conditions before accepting.
Mistake 5: Not Knowing How to Use Your Itinerary for Travel Logistics
Many travelers overlook the itinerary's potential as a tool for planning ground transportation, hotel bookings, and other essential travel arrangements.
Ground Transportation Planning
Your itinerary provides precise arrival times and airport locations, which are vital for pre-booking ground transportation. Whether you're arranging a taxi, rideshare, shuttle service, or rental car, knowing your exact arrival details ensures you book the correct service for the correct time. This prevents last-minute scrambling and potential surge pricing or unavailability at your destination.
For example, if your flight arrives late at night, you might need to book a service that operates 24/7. If you are arriving at a smaller airport, options might be limited, making pre-booking even more critical. Always factor in potential delays when scheduling pickups, perhaps adding a buffer of 30-60 minutes.
Hotel and Accommodation Booking
Hotels often require an estimated arrival time for check-in, especially for late arrivals. Your flight itinerary provides this information. Many hotels also have policies regarding late check-ins, and providing your flight details can help them manage your reservation effectively, ensuring your room is held if your flight is delayed.
When booking accommodation, you can confidently provide your arrival date and approximate time. This accuracy helps hotels manage room availability and staffing. If your flight is significantly delayed or canceled, you can use your itinerary to communicate with your hotel and adjust your reservation accordingly, potentially avoiding no-show fees.
Using your itinerary to inform accommodation bookings saves time and reduces the risk of unexpected charges.
Visa and Entry Requirements
While your itinerary doesn't directly list visa requirements, the destination country and transit points specified on it are critical for determining what documentation you need. For international travel, accurately noting the arrival country and any transit countries is the first step in researching visa, passport validity, and other entry requirements. Immigration officials may also ask to see your onward or return itinerary.
Different countries have different rules about passport validity (often requiring at least six months beyond your stay) and may require proof of onward travel. Your itinerary confirms your departure from the country, satisfying this requirement for many nations.
Travel Insurance Claims and Support
In the unfortunate event of a flight delay, cancellation, or lost luggage, your flight itinerary is a primary document required when filing a claim with your travel insurance provider. It serves as proof of your booked travel arrangements and the original scheduled times. Keep digital and physical copies readily accessible.
When contacting airlines or travel support about issues, having your itinerary at hand allows you to quickly provide all necessary details about your booking, including flight numbers, dates, and passenger information, expediting the resolution process.
Mistake 6: Forgetting to Save or Print Your Itinerary
A surprisingly common error is failing to keep a accessible copy of the itinerary, leading to panic when digital access fails or specific details are needed offline.
Digital Accessibility and Offline Access
In today's digital age, most travelers rely on their smartphones for itinerary access. However, mobile phone batteries die, data connections can be spotty, and apps might glitch. It's crucial to ensure your itinerary is accessible offline. Most airline apps allow you to download your booking details for offline viewing. Similarly, saving a PDF copy to your phone's local storage or a cloud service like Google Drive or Dropbox is a wise precaution.
Consider saving digital copies to multiple devices if possible. For instance, sync your itinerary to your phone, tablet, and perhaps a laptop. This redundancy ensures that even if one device fails, you have access to your vital travel information.
Ensuring offline access to your itinerary is paramount for seamless travel.
The Value of a Printed Copy
Despite digital advancements, a printed copy of your itinerary remains a reliable backup. It requires no battery power, no internet connection, and is easily accessible even if all your electronic devices fail. Keep it in a secure but easily retrievable location, such as a travel wallet or a dedicated folder in your carry-on luggage. It's particularly useful for situations like check-in at airports with limited connectivity or when dealing with officials who may prefer a physical document.
A printed copy also serves as a quick reference point. You can easily jot down notes on it, such as gate numbers or boarding times, without draining your phone battery or needing an app. For longer trips with multiple flights, a printed itinerary can provide a clear overview of your entire journey at a glance.
Organizing Travel Documents
Beyond the itinerary, having a system for organizing all travel documents is essential. This includes passports, visas, hotel confirmations, rental car bookings, and any relevant insurance details. A travel wallet or a dedicated folder helps keep everything in one place, reducing the chances of misplacing important papers. For digital documents, a well-organized cloud storage system or a dedicated travel app can be invaluable.
When traveling, it's a good practice to have your most critical documents (like your passport and itinerary) in your carry-on bag, while less critical items might be stored more securely. This ensures that even if your checked luggage is lost, you still have access to the essentials for your journey.
Sharing Itinerary Information
You might need to share your itinerary details with family, friends, or colleagues. This could be for them to track your arrival, for an emergency contact, or for someone managing your travel arrangements. Many airline apps and websites offer a 'share itinerary' function. You can also manually forward the email confirmation or a PDF copy. Ensure you share the most up-to-date version of your itinerary.
When sharing, consider the privacy implications. Only share necessary details and with trusted individuals. For instance, you might share flight times and arrival details with a pickup contact, but not necessarily your full booking reference number unless it's essential for them to manage your booking.
Mistake 7: Not Understanding Flight Numbers vs. Booking References
Confusing a flight number with a booking reference number is a common error that hinders effective itinerary management and retrieval.
Defining the Booking Reference (PNR)
The booking reference number, often called a PNR (Passenger Name Record) or confirmation code, is a unique alphanumeric code assigned to your entire booking. It links all passengers and all flights within a single reservation. This code is your primary key to accessing and managing your booking on the airline's website or app. It's specific to your reservation and is used to identify you as a customer of the airline for that particular trip.
When you make a booking, whether for one flight or multiple legs, you receive one booking reference. This reference is crucial for making any changes, selecting seats, or checking in. It acts as a master key to your reservation details.
Always use your booking reference number and last name to access your full itinerary.
Defining the Flight Number
A flight number is a specific code assigned to a particular flight route on a particular day. It typically consists of an airline's two-letter or three-letter code followed by a series of digits (e.g., DL456 for Delta Air Lines). Each flight segment in your itinerary will have its own flight number. This number is used for tracking flight status, checking schedules, and for airport signage.
While your booking reference covers your entire trip, flight numbers are segment-specific. For example, if you have a flight from New York to London, and then London to Paris, you will have one booking reference but two different flight numbers (one for each leg).
When to Use Which Identifier
You use the booking reference number (PNR) and your last name to: access your entire booking, manage your itinerary, change flights, select seats, add services, and check in online for all segments of your trip. It's your universal key to your reservation.
You use the flight number to: check the specific status of a particular flight (delays, gate, etc.), look up flight schedules, find your flight on airport departure boards, and sometimes for communication with airport staff about a specific flight. It identifies a specific journey in the air.
What is a Flight Number?
A flight number is essentially the airline's internal identifier for a specific service between two points on a given date. It helps the airline manage its operations and provides passengers with a clear way to identify their intended flight. For instance, if you need to know if flight UA870 is on time, you would look up 'UA870' rather than your booking reference.
When you search for flights on an airline's website, you often see flight numbers listed alongside times and routes. These are the identifiers that travelers will use throughout their journey, from booking to arrival.
Proactive Itinerary Management for Stress-Free Travel
Adopting a proactive approach to managing your flight itinerary can transform travel from a source of anxiety into an efficient, enjoyable experience.
Create a Travel Checklist
Develop a comprehensive travel checklist that includes reviewing your itinerary as a key step. Assign specific times to check your itinerary: immediately after booking, a week before departure, 72 hours before, 24 hours before, and again on the day of travel. This structured approach ensures that you are always aware of your flight details and any potential changes.
Your checklist might also include items like verifying passport expiry, checking visa requirements, confirming hotel bookings, and arranging airport transportation. Integrating itinerary checks into this routine makes it a natural part of your travel preparation.
Utilize Technology Wisely
Leverage airline apps, digital calendars, and flight tracking services. Set reminders for check-in periods and for reviewing your itinerary. If your airline offers a 'track my flight' feature or allows you to add flight details to your calendar, use it. These tools provide timely updates and integrate travel information seamlessly into your daily life.
However, always use technology as a supplement, not a sole source. The underlying principle is to have multiple layers of confirmation and access, ensuring you are never left without crucial information.
Proactive management means anticipating issues rather than reacting to them.
Communicate with Your Travel Companions
If you are traveling with others, ensure everyone has access to the itinerary or at least the critical details. Coordinate meeting times at the airport, shared transportation, and accommodation check-ins. Clear communication among travel companions minimizes confusion and ensures everyone is on the same page regarding flight times, gate information, and layover plans.
For group bookings, designate one person as the primary point of contact for itinerary management, but ensure others have a way to access the information if needed. This avoids a single point of failure in communication.
What to Do If You Discover an Error Late
If you discover a critical error on your itinerary very close to departure (e.g., name mismatch on the day of travel), act immediately. Contact the airline's customer service and explain the situation clearly. Be polite but firm, and be prepared for potential challenges. In some cases, you might need to visit the airline's ticket counter at the airport to resolve urgent issues. While it's always best to catch errors early, prompt action can sometimes salvage the situation.
Be aware that airlines have varying policies on correcting errors close to departure. For name issues, it might be impossible to change without rebooking, which could incur significant fees. However, for other discrepancies, a helpful agent might be able to assist.
Frequently Asked Questions About Flight Itinerary Lookup
Here are answers to common questions about accessing and managing your flight itinerary.
How do I look up my flight itinerary?
To look up your flight itinerary, visit the airline's official website or mobile app. Navigate to the 'Manage My Booking' or 'My Trips' section. You will need your booking reference number (confirmation code or PNR) and your last name to retrieve all your flight details.
Can I look up my flight itinerary with just my name?
Generally, no. While your name is required, it must be used in conjunction with your booking reference number (PNR) or confirmation code. This combination ensures that only the correct passenger can access their specific itinerary details and prevents unauthorized access to bookings.
What is the difference between a booking reference and a flight number?
A booking reference (PNR) is a unique code for your entire reservation, linking all passengers and flights. A flight number identifies a specific flight segment on a given date (e.g., UA123). You use the booking reference to manage your whole trip and the flight number to track a specific flight's status.
How often should I check my flight itinerary for updates?
It's advisable to check your flight itinerary regularly, especially in the days leading up to your trip. Review it at least 72 hours before departure, again 24 hours before, and once more on the day of travel. Airlines can change schedules, and these updates are crucial to catch.
What should I do if my flight itinerary is incorrect?
If you find an error on your flight itinerary, contact the airline immediately. Provide them with your booking reference number and explain the discrepancy. Minor corrections can often be made, but prompt action is necessary to avoid issues during check-in or travel.
Is my booking confirmation email my flight itinerary?
A booking confirmation email is a starting point, often containing your booking reference. However, the official flight itinerary is typically found on the airline's website or app, providing more detailed and up-to-date information. Always cross-reference with the airline's direct portal.
How can I access my flight itinerary if I lose internet access?
Ensure you download your itinerary to your phone or device for offline access. Many airline apps allow this, or you can save a PDF copy to cloud storage or local files. Carrying a printed copy is also a reliable backup for offline situations.
